%TREEOUTLEN  Lengths of tree subbands
%   Usage:  Lc = treeOutLen(L,doNoExt,wt)
%
%   Input parameters:
%         L       : Input signal length.
%         doNoExt : Flag. Expansive = false, Nonexpansive=true  
%         wt      : Structure containing description of the filter tree.
%
%   Output parameters:
%         Lc : Subband lengths.
%
%   Lc = TREEOUTLEN(L,doNoExt,wt) returns lengths of tree subbands given
%   input signal length L and flag doNoExt. When true, the transform is
%   assumed to be non-expansive.
%   For definition of the structure see WFBINIT.
